演唱：Sarika Patanawat 作词&作曲：化学之国 Do you think elephants are pure The definition of chemical formula indicates the amount of constituent atoms Its usage is element symbols and numbers The composition of pure substances is fixed Neither symbols nor numbers can be changed The substance it represents is pure A substance is expressed by only one chemical formula Just like an elephant has only one name Whether ionic compounds or covalent compounds But some chemical formulas are empirical Represents the proportion of atoms in a substance Like two elements in sodium chloride The number ratio of these two elements is one to one If elephants are chemically pure Then there is a unique chemical formula Considering the proportion of material composition There is a probability that there will be two expressions There is also to determine the type of compound first Is to judge ionic compounds or covalent compounds But also relate to isomers with different arrangement Just like isotopes have the same elements The composition of matter is determined by experiments A substance made up of molecules is called a molecular formula But if it's a chemical formula on a simple substance That number means the number of constituent atoms If it is in the chemical formula of metallic simple substance There are solid nonmetallic simple substances It is directly represented by element symbols The same is true for rare gases If elephants are chemically pure Then there is a unique chemical formula Considering the proportion of material composition There is a probability that there will be two expressions There is also to determine the type of compound first Is to judge ionic compounds or covalent compounds But also relate to isomers with different arrangement Just like isotopes have the same elements Due to that simple metal and solid nonmetallic structure It is too complicated so to use element symbols as chemical formulas There are also rare gases that are directly composed of atoms As well as simple metal and solid nonmetal In fact elephants have many chemical elements If elephants are chemically pure Then there is a unique chemical formula Considering the proportion of material composition There is a probability that there will be two expressions There is also to determine the type of compound first Is to judge ionic compounds or covalent compounds But also relate to isomers with different arrangement Just like isotopes have the same elements
